Poyet makes second Sunderland signing with capture of Argentinean international
Sunderland boss Gus Poyet has made his second signing of the transfer window by acquiring Argentina defender Santiago Vergini on loan until the end of the season.
After signing full-back Marcos Alonso from Fiorentina on the same terms earlier this month, Poyet has added centre-back Vergini from Uruguayan side Atletico Fenix.
The 25-year old has previously played with Olimpia in Paraguay and Verona in Italy, while most recently he was on loan with Argentine side Estudiantes after a spell with Newell's Old Boys.
Vergini's one and only cap for his country came in 2012.
